1950s, Loving Your Enemies (November 1957)
Context: There is something within all of us that causes us to cry out with Ovid, the Latin poet, "I see and approve the better things of life, but the evil things I do." There is something within all of us that causes us to cry out with Plato that the human personality is like a charioteer with two headstrong horses, each wanting to go in different directions. There is something within each of us that causes us to cry out with Goethe, "There is enough stuff in me to make both a gentleman and a rogue." There is something within each of us that causes us to cry out with Apostle Paul, "I see and approve the better things of life, but the evil things I do." So somehow the "isness" of our present nature is out of harmony with the eternal "oughtness" that forever confronts us. And this simply means this: That within the best of us, there is some evil, and within the worst of us, there is some good. When we come to see this, we take a different attitude toward individuals. The person who hates you most has some good in him; even the nation that hates you most has some good in it; even the race that hates you most has some good in it. And when you come to the point that you look in the face of every man and see deep down within him what religion calls "the image of God," you begin to love him in spite of. No matter what he does, you see God’s image there. There is an element of goodness that he can never sluff off. Discover the element of good in your enemy. And as you seek to hate him, find the center of goodness and place your attention there and you will take a new attitude.

Attributed to Emerson in Life’s Instructions for Wisdom, Success, and Happiness (2000) by H. Jackson Brown Jr., as well as numerous on-line sources since, the article "The Purpose of Life Is Not To Be Happy But To Matter" at the Quote Investigator https://quoteinvestigator.com/2014/11/29/purpose/ indicates that this quote is probably derived from various statements first made by Leo Rosten, including the following words delivered at the National Book Awards held in New York in 1962: "The purpose of life is not to be happy — but to matter, to be productive, to be useful, to have it make some difference that you lived at all."

Walden (1854)
Context: A living dog is better than a dead lion. Shall a man go and hang himself because he belongs to the race of pygmies, and not be the biggest pygmy that he can? Let every one mind his own business, and endeavor to be what he was made. Why should we be in such desperate haste to succeed, and in such desperate enterprises? If a man does not keep pace with his companions, perhaps it is because he hears a different drummer. Let him step to the music which he hears, however measured or far away.<!--pp.366-367

Part I, Essay 23: Of The Standard of Taste
Essays, Moral, Political, and Literary (1741-2; 1748)
Source: Of the Standard of Taste and Other Essays
Context: Beauty is no quality in things themselves: It exists merely in the mind which contemplates them; and each mind perceives a different beauty. One person may even perceive deformity, where another is sensible of beauty; and every individual ought to acquiesce in his own sentiment, without pretending to regulate those of others.

Context: Many have imagined republics and principalities which have never been seen or known to exist in reality; for how we live is so far removed from how we ought to live, that he who abandons what is done for what ought to be done, will rather bring about his own ruin than his preservation.
